A few weeks ago, I wrote a detailed post on our backyard apple trees. They were planted in 2006 and so are now five years old. We have been training them into an espaliered planting and recently I got the jute out and tied the new shoots onto the support wires. The trees are currently loaded with blossoms and sometime later in summer I'll prune them, probably around February.
